This paper tries to summarize the talk held at the opening event of the SENAI institute for electrochemistry in Curitiba, Brazil on September 16th 2013. It gives an application-oriented overview over existing principles of electrochemical sensors. Furthermore it describes step by step the development of an electrochemical sensor, it shows the differences between the requirements for gas phase and liquid phase detection, gives examples for open sensor designs and membrane covered sensors and last but not least the talk discusses two different kinds of evaluation, that is the trace detection for specific substances and the pattern recognition for complex matrices.
